GEORGE HERBERT KING, F WOODSTOCK, ONTARIO, CANADA.

Vacuum-CLEANER.

Specication of Letters Patent.

Application led January 13, 1912. i Serial No. 671,088.

l KING, ofthe city of Woodstock, in the county ofy Oxford, in the Province of Ontarlo, Canada, have invented cert-ain new and useful Improvements 1n Vacuum-Cleaners, of which the following is the specification.

My invention relates to improvements in` vacuum cleaners and has for its object toV provide a structure which is compact, simple and etlicient and one which is comparativelyl inexpensive to manufacture.

The abo-ve and other objects will be apparent when the specification is -considered together. with the accompanying drawings, in which- Figure 1, is a vertical section through the vacuum chamber and co-acting parts. Fig. 2, is a similarview to Fig. 1 taken at right angles thereto. Fig. 3, is a perspective de-` tail of the securing device for the vacuum l chamber closure.

, In the drawings like letters of reference indicate corresponding parts in each figure.

A is the vacuum chamber provided with a dust inlet tube Aconnected in the usual manner to a suitable dust collecting nozzle, The vacuum chamber comprises a bottom board A2, side walls A5 and end walls A4 and A and a top cap or closure A detachably secured to the top of the chamber by means which I will hereinafter describe.

The vacuum chamber rests upon the main board D on the extended end'D of which the operator stands.

F and F are bellows secured to the end boards A4 and Ai of the vacuum chamber.

F2 and F 3 are ports extending from the lower end of the bellows through the boards At and A5 to below the board Av2 so as to communicate with the atmosphere.

/F4 are valves for the portsF2 and F3.

F is an intermediate Wall extending across the vacuum chamber intermediately of its height.

F7 is an orifice extending through the wall F.

F8 is a vertical wall extending upwardly from the wall F in proximity with the top of the vacuum chamber.

G are ports extending into the vacuum .chamber between the wall F and one of the 'walls A3 of the chamber. The ports G are provided with valves G. It will be understood on referring to Fig. 1 of the drawings that the ports G connect the top portion of lrach bellows F and Fto the Vacuum chamer. J is an operating lever connected by a link J to the bellows F. The bellows F and F are provided with depending lugs J2 connected together by a link J s.

K are a series of screens extending horizontally over the orifice F7 between one end board A3 and the wall F".

K is an arc-shaped spring a ainst which the cap .A7 is held so as to hol l the screens tightly down in place.

The construction which I have hereinbefore described is covered by a previously tiled application. such construction so as to show the connection of the parts which I now claim to be new therewith. Such novel parts I will now describe.

L is a bag formed of cotton or other suitable material suitable for screening the dust. The bag L extends around t-he orifice F1 and is secured thereto at ,the top to the edge of the opening F Tby a suitable frame L.

M is a. straight deflectin board which extends downwardly atan o tuse angle to the intermediate wall F so that as the dust laden air enters throu h the inlet A it strikes against the boar M and is defiected downwardly in the direction of arrow and then upwardly through the depending screening bag L.

It will, of course, be understood that the heavy dust falls to the bottom of the chamber A while 'the lighter dust is carried upwardlyand is caught by the screening bag L. The screening bag L will prevent the screens by continued operation of the machine becoming clogged. As the interstices become clogged the bag will alternately be drawn up and released so as to pulsate with the suction of the machine thereby automatically shaking itself free of dust.

N isa board extending between the wall Fa and one of the walls Aa and from the wall A* to the wall A. The board N is rovidedwith suitable perforations N an Nz is a la er of suitable filtering fabric whlch is preferably folded in several layers and laid on top of the board N so as to cover the perforatins N. By this means the filter- Patenteli Feb. 25, 1913. V

I have only described ing material is spread over a 4wide area and the case in my previous construction thereby preventing air passing freely through and making the machine hard to work.

O are plates secured to each corner of the closure or cap A6. The plates O are prof vided with inclined portions O terminating in depressions O2.' Y

P is a bail forming a handle P. The ends of the bail extend downwardly at P5 .to each side of the vacuum chamber A and are piv-- otally connected thereto by any suitable screws'Pi. Between the handle P and the downwardly extending portion P5 is a hori-v zontal portion P3. `It will be understood that when it is-necessary to remove the cap or closure the handle P is forcedV outwardly so as to swing the bail P on its -pivot formed y by the screws P2 and thereby force the horizontal portion P3 out of the depression 0 2. When it is desired to again place the closure into position the handles P are forced together so that the horizontal portions P3 engage the inclined portion O of the plates O andby the continued inward movement of the handle P such portions P3 are forced into the depressions O2.

rendering the vacuum chamber leaky and destroying the inward suction ofthe air to draw the dust'through thetube A into the chamber.

. From this description .it will be seen that I have devised a very simple means whereby any danger of clogging the screens and obstructing the passage of air through the iltering material is obviated, thereby rendering the work of the machine more easy and preventing any danger ofthe deflector'board becoming clogged or the casing leaky.

What I claim as Imy invention is.

In a vacuum cleaner, the combination with the vacuum chamber,y of an intermediate cross wall having an .orice therein, a vertical wall extending upwardly from the inter-mediate wall in proximity with the to of the cleaner and between the end boar s of the vacuuml'chamber, a suction port. lo cated in the end walls above the cross wall and between the vertical wall andthe wall of the vacuum chamber, and a perforated cross wall extending between the -vertical wall and the wall of the vacuum' chamber, and a layer of ltering material designed to cover the' perforated cross wall, as' and for the purpose specified. y
